Common cold

Symptoms of a cold 

The symptoms of a cold usually develop within a day or two of becoming infected.

The main symptoms include:

• a sore throat
• a blocked or runny nose
• sneezing
• a cough
• a hoarse voice
• generally feeling unwell

Less common symptoms of a cold include:

• a fever (high temperature) - generally considered to be 38°C (100.4°F) or over (see fever in children)
• a headache
• earache – severe earache may be a sign of a middle ear infection
• muscle pain
• loss of taste and smell
• mild irritation of your eyes
• a feeling of pressure in your ears and face  

The symptoms are usually at their worst during the first two to three days, before they gradually start to improve.

In adults and older children, they usually last about seven to 10 days, but can last longer. A cough in particular can last for two or three weeks.

Colds tend to last longer in younger children who are under five, typically lasting around 10 to 14 days.

Telling the difference between cold and flu

Cold and flu symptoms are similar, but flu tends to be more severe.

Cold symptoms:

• appear gradually
• affects mainly your nose and throat
• makes you feel unwell, but you're OK to carry on as normal (for example, go to work)

Flu symptoms:

• appear quickly within a few hours
• affect more than just your nose and throat
• makes you feel exhausted and too unwell to carry on as normal

What to do 

There's no cure for a cold, but you can look after yourself at home by:

• resting, drinking plenty of fluids and eating healthily
• taking over-the-counter painkillers, such as paracetamol or ibuprofen, to reduce any fever or discomfort
• using decongestant sprays or tablets to relieve a blocked nose
• trying remedies such as gargling salt water and sucking on menthol sweets

Many painkillers and decongestants are available from pharmacies without a prescription. They're generally safe for older children and adults to take.

However, they might not be suitable for babies, young children, pregnant women, people with certain underlying health conditions, and those taking certain other medications.

Speak to a pharmacist if you're unsure.

When to see your GP 

If you or your child has a cold, there's usually no need to see your GP as it should clear within a week or two.

You only really need to contact your GP if:

• your symptoms persist for more than three weeks
• your symptoms get suddenly worse
• you have difficulty breathing
• you develop complications of a cold, such as chest pain or coughing up bloodstained mucus

You should see your GP if you're concerned about:

• your baby
• an older person
• if you have a long-term illness such as a lung condition

If your GP surgery is closed, you can also contact GP out of hours service for advice, if you are concerned and believe the symptoms mean that you are unable to wait to talk to your own GP.

Stop the spread of colds

Viruses cause colds and coughs. When you cough or sneeze you send tiny droplets of infected saliva into the air. This can pass viruses to other people.

To stop spreading germs:

• always carry tissues
• use a tissue to cover your nose and mouth every time you cough or sneeze
• use tissues once and throw them in a bin
• wash your hands regularly, and as soon as possible after sneezing or coughing

Help yourself feel better 

You can take some steps to reduce the effects of winter colds:

• keep warm by wearing layers of thin clothing
• take the recommended dosage of paracetamol or ibuprofen to ease aches and pains and keep your temperature down
• increase your fluid intake and reduce caffeinated drinks, such as tea, coffee and cola

There are different remedies available in pharmacies. 

You should follow a pharmacist’s advice if you are already taking painkillers or other medicines.

Always check the instructions on the bottle or packet carefully, and never exceed the recommended dose.

Never give aspirin to children under the age of 16.

Boost your immune system 

Your immune system helps you fight viruses.

To help your immune system:

• eat more fruit, vegetables and wholegrain foods 
• don't smoke or use recreational drugs as these stop your immune system from working properly  
• exercise regularly
